FLUSH-OUT.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed June 11, 191B. Serial No. 773,029.

To all whom t may concern.'

Be it known that I, DAVID GIBBs, a citiaen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Flush-Outs, ofwhich the following is a specification.

This invention relates to a flushing valve for water-closet tanks.

It is the object of this lnventionto provide a iushing valve of theloose ball type,

with means for lifting the ball from its seat from'its underside, whichis so constructed as to obviate disposing the valve operating mechanismwithin the tank.`

A further object is to provide a simple and eiiicient flushing valvewhich is durable and not liable to get out of order. l

The invention primarily resides in a tank having a sloping bottomleading to a flushout pipe, a valve seat at the mouth of the fiush-outpipe, a loose ball adapted to rest on said seat to prevent the dischargeof liquid from the tank, and means disposed in the flush-out pipeoperable by a hand lever exterior thereof for lifting the ball from itsseat.

The invention further consists of the parts and the construction andcombination of parts as hereinafter more fully described and claimed,having reference to the accompanying drawing, in which- Figure 1 is avertical section of one form of the invention. Fig. 2 is a section inele'- vation on the line a-a of Fig. l. Fig. 3 is a vertical section ofa modified form of the invention. Fig. 4 is a horizontal section andelevation on the line b-b of Fig. 3. Fig. 5 is a horizontal section onthe line c-c of Fig. l.

lIn the drawings, A represents the bottom of a tank or reseivoir of anysuitable construction; the bottom A being inclined downwardly toward itscenter. Mounted on the bottom A at its lowest point is a tubular vmember 2, which is threaded on its exterior and adapted to be vengagedby a threaded sleeve or union'l on a nipple 4 threadedl in the upper endof the elbow 5. The elbow 5 is connected at its lower end with a bowl orother structure, not shown. The member 2, nipple 4, and elbow 5constitute a Hushout pipe leading from the bottom A of a tank to asuitable point'of discharge.

Interposed between the ends of the member 2 and, the nlpple 4 is aspider or ring 6,

which is supported on the up er end of the nipple 4 and is held in placey a washer 7 clamped between the ends of the member 2 and the nipple 4by means of the union 3. The ring 6 is formed with transverse ribs whichsupport a central perforated member 9 which serves as a guide andsupport for a vertically disposed rod 10. The rod 10 is threaded at itsupper end and is screwed into a collar 11 on which a ring 12 is sup-'ported on outwardly and upwardly extending arms or standards 13 on thecollar 11. The ring 12 is designed to normally contact the underside ofa loose ball 14 seated on the upper open end of the member 2, the ball14 forming a valve and the member 2 a seat therefor.

In the form of the invention shown in Figs. 1 and 2, the bar 10 isformed with rack teeth 15, on one of its vertical edges, which teethmesh with a toothed segment 16 mounted on a rock-shaft 17 extendingacross the interior of the elbow 5 and passing through a stuiiing-box 18in the latter. The bar 10 is retained in mesh with the segment 16 bymeans of a guide yoke 19 secured to the interior of the elbow 5; the bar10 passing between forked members on the guide yoke 19, as shown in Fig.1.

In the form of the invention shown in Figs. 3 and 4,' the lower end ofthe bar 10 is pivotally connected to an arm 16 secured to the shaft 17.Wound on the bar 10, and bearing between the guide member 9 and a pin 20on the bar 10, is a spring l21 which acts to normally retain the bar 10in its lowermost position. The shaft 17 is provided with a hand lever22, exterior of the elbow 5, byv means of which the shaft 17 may berocked.

lVhen the ball 14 is disposed on its seat and the tank is filled withwater, or other liquid, the ball will be held in its seated position bythe weight of the liquid there' above. l lVhen it is desired todischarge the this occurs the ball, by reason of its being therebyleaving the upper end of the iiushj' out open so that the contents ofthetank constructed in such manner as to float, will lrise to thesurface of the liquid in the tank,

will be rapidl discharged therefrom.

Upon releasing t e handle 22 the spring 21 will operate to restore therod 10 to its normal' lowermost position. When the tank is empty theball 14 will be caused to roll down the inclined bottom A. into positionon the valve seat member 2, thus closing communication between the tankand ilush out pipe so that the latter may be refilled. p

By thus constructing the valve operating mechanism and disposing itwithin the lush,

out pipe, and by forming the tank with a sloping bottom A, the use ofcages for guiding and directing-theball 14 and the valve operatingmechanism within the tank is dispensed with.

In some instances the handle 22 may be weighted sufficiently to restorethe bar 10 to its normal position on releasing the handle, in whichevent the spring 21 may be dispensed with.

Having thus described my invention, what ent 1s-' l v l In combinationwith a tank having a discharge and a tube therein, a l spider connectedclaim and ldesire.tesecure by Letters Patto the tube, a rod slidable inthe. spider, a'

ball, a ring to support the ball, an interiorly threaded collar havingits base seating on top of the spider, spaced divergent arms connectedto the collar and ring, a rod slidable through'the spider and threadedlyconnected to said collar, a spring connected to and surrounding the rodand abutting the lower side of the spider, a pivoted upwardlyA ,movablehandle to actuate the rod and means to operate the rod from the handle,said handle being limited in its downward movement b engagement of thecollar with the upper ace of the spider.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses. p

DAVID GIBBS.
